Issue #1790 has been updated by Matej Vadnjal.
I think I can add some info on this issue.
I had the same problem with iptree6 for a while. I think I tracked this bug
down, but I haven't tested the fix, cause the problem disappeared and I forgot
to file a bug report.
iptree is a Net::Patricia object. This object gets serialized by
Storable::nfreeze and cached in the netdot database by the DataCache model.
Sometimes when a tree is frozen the last byte of the frozen object can be 0x20
in hex or Space in ASCII table. This gets written to the database fine. When
this DataCache record gets retrieved from the DB however it is missing the
trailing 0x20 byte. In this case the Storable::thaw method fails and the tree
cannot be used.
Rebuilding the tree will again result in the same data when frozen since no
Ipblock changes cannot be preformed.
I believe the issue is that Class::DBI trims data when read from the database.
When I was looking at the database record it looked like the data was written
properly - IE the trailing space was there.
Now, looking at lib/Netdot/Model/DataCache.pm it is my understanding that the
frozen tree data should be encoded into base64 before saved into the database
and decoded. But as I was investigating it looked like the data is base64
encoded in the DataCache object attribute, but the data written to the DB is
not. Probably again an issue in Class::DBI I imagine.
All my tests were done on netdot 1.0.4 with Mysql 5.1.71 and Class::DBI 3.0.17
(which seems to be the latest available).
In all likelihood this is the same problem as Alen has.

Issue #1790 has been updated by Matej Vadnjal.
File iptree.pl added
Alen: Here is a script to check if your issue is the same as mine was. Copy the
script into your netdot folder (probably /usr/local/netdot) and run it like
this:
perl iptree.pl 4 <netdot_db_username> <netdot_db_password>
All the binary data in last chars lines should be the same. If it is not you
probably encountered the same bug as me.
